Read text and edit pdf document in IAC

[tataxin@adobeforums.com]

Hi all,

I'm newbie in Acrobat SDK, now I start with IAC (InterAppCommunication) in C#.

Is there anyway to read each line from a pdf document? And how to directly edit a pdf document?

I already look at all examples in \InterAppCommunicationSupport\C#Samples but it's seem to be nothing helpful.

Please give me some sample source codes or links.

Thank you in advance, :)

Well, no, because PDF documents don't have "lines". It is not a text format. The text may visually be arranged in lines like in a text file, but that by no means guarantees that is how they are stored in the PDF. Have you read any of the PDF Reference (ISO 32000-1 now that Adobe no longer controls the PDF spec) to understand how a PDF stores text before you start a project like this?

Thank you for your reply, PDL!

I have never read that document. I'm going to read it now and come back to project later.

But there're some softwares can convert pdf document that keep structure. Do you know how to do that?

Yes, but it cannot be done with IAC. You would need to write a plug-in that gets each textual element on the page, gets the coordinates it will be drawn to, and then makes its own decisions on what the structure should be based on those coordinates. IAC does not have this level of access.

Ah, I see!! So I have to start with plug-in projects.
Thank you very much, PDL!!
